If you haven't read The Dresden Files, then you need to set aside a chunk of your immediate life and do so.
The 13th book in this series is the best yet. The characters continue to grow, maturing into the next book. Master Writer Jim Butcher has done an excellent job again of weaving a murder mystery together - setting it up to see if his readers can guess the missing pieces, and then revealing them at the proper time. The book came to close with the immediate intrigues settled, while still leaving some over-arching conflicts set up for the next book.
